To all 'whom 'it may concern:

Be it known that I, CHARLES J. GUsTAFsoN, a sub-` ject of the .King of Sweden, and a resident oi the city of' as fully described in connection with the accompanying drawing and specifically pointed out in the claims? Figure l is a partly sectional plan view of a portion of .a handle-barof a motor-cycle having'my invention applied thereto; the controlling lever only of the motor with which the cycle is provid ed being indicated. Fig. 2 is a partly sectional elevation of the same. I Fig. 3 is a separate view oi the connecting-shaft portions 10- cated adjacent to the rotating grip.

Only the head 2 of a motorcycle frame is shown in the drawings; the motor controlling lever or member 3 through which the required movements may be conveyed to the motor, lbeing mounted, as indicated, upon a bearing pin 4 on said frame head, so as to be rocked thereon by the rotation of the hand grip 5 uponthe rearwardly bent end of the swinging handle-bar 6 fixed I as usual to the steering fork the frame head.

My invention relates particularly to that type of operating mechanism for the motor-controlling lever 3, in

. which a rotary connecting shaft is employed Vbetween the rotary grip and said lever. In my improved mechanism, as shown, the operating connection between the grip and said lever-connecting rotary shaft, is arranged exteriorly of the handle-bar so that the latter may be made either otubular or solid material as preferred'. A grip-sleeve 10, rotatably tted upon the rearwardly bent end portion of said bar, is adjustably retained upon the latter, as shown, by means of a screw-threaded endpiece ll at the extremity of said bar, the sleeve being provided with a retaining collar l2 through which said` end piece passes, and being adjustable lengthwise upon Y the bar by nuts- 13 upon the projecting end piece. To

improve the appearance of the grip end piece and the nuts thereon are preferably inclosed by the rearwardly extended grip-sheath 1la as shown. The inner end of the grip sleeve l0 is provided with a toothed edge forming a face-wheel 14 around the handle-bar.

The rotary shaft extending to the motor-controlling lever 3, is made up oi several parts forming an approximately straight-line shalt substantially at right angles to the airis ofthe gripbearing 'portion of the handlebar.

It co'mprises a journal-piece 15 which extends'through va transverse opening 16 in the handle bar, adjacent the toothed end'14 ofthe grip-sleeve; said journal-piece as shown being formed with an exterior head l7, and having fixed to its inner end a cogwheel-and-joint piece 18, 19; the cog-wheel 18 being arranged in mesh with the properly adjusted face-wheel 14 oi the grip-sleeve, While the joint end 1 9' is pivotally connected to a shaft section 20 arranged in telescopingengagement with a shaft section 21 extending tothe motor controlling lever 3, to which latter it is pivotally connected at 22.

The headed journa1-piece'15 of the shaft, thus mounted transverselyv in the handle-bar with its cog-wheel 18 located close against the inner side oi the bar, is rotated by the toothed grip-sleeve in a most simpleand positive manner, and transmits ,this rotary movement in like' manner, in all positions oi the handle bar,

through its telescoping pivoted extensions tothe motorcontrolling lever. Both the grip engagement with the shaft, entirely outside of the handle bar, and the 'shaft connection to the motor controlling lever, are very simple and advantageous in construction and operation, and present a very neat appearance.

What I claim isz- 1. In .a grip-operated controlling mechanism for motor cycles, the, combinatio'n with a handle-bar provided with a' transverse shaft bearing, and a motor-controlling',r lever, of an operating shaft for the latter having its opposite end mounted in said Ytransverse shaft bearing and provided with a cog-wheel adjacent the hand1ebar,and a rotatablegrip-sleeve on the latter having a facewheel on its inner end arranged in mesh with said cog-wheel.

2. In a grlp-operated controlling mechanism fo'r motor cycles, the combination witha handle-bar provided with a transverse shaft bearing, and :1 motor controlling lever, of an operating shaft for the latter comprising a headed journal-piece mou`nted in said transverse bearing, a cog-wheel and joint piece fixed to said end-piece, and telescope-secl tions pivotully connected to said joint-piece and controlling lever respectively, and. a 'rotatable grip-sleeve having a face-wheel on its inner end arranged in mesh with said cog-wl1eel. j

3. In a grip-operated controlling mechanism for motor cycles, the combinntion'with a motor-controlling.lever, an operating shaft therefor, and n handle-bar having a screwbnr having a .retaining collar strung upon said end-piece, adjusting nuts upon the latter, and a gripping sheath upon said sleeve extending beyond said end-piece to inclose the saine, substantially as set forth.

v In testimony whereof, 'I ailx my signature, in -the presence of two witnesses.
